ELECTRIC PUNCH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 383,4:85, dated May 29,1888.

Application filed November 20, 1886. Serial No. 219,533. (No modelJ Toall whom it may concern:

Be it known that I, AUGUSTUS O. PALMER, a citizen of the United States,residing at Utica, in the county of Oneida and State of New York, haveinvented certain new and useful Improvements in ElectricPunch-Registers, of which the following is a specification, referencebeing had to the accompanying drawings.

My invention relates to electric registeringmachines by which holes arepunched in a strip of paper for fire-alarm, police, or other purposes;and it consists in the devices and their combinations hereinafterdescribed, and specifically pointed out in the claims.

In the drawings-two sheets-Figure 1 is a front view of an electricpunch-register embodying my invention. Fig. 2 is a rear view, and Fig. 3a plan, of the same. Fig. at is a vertical longitudinal section aboutmidway between the front and rear plates, and shows the parts held inplace within the machine on the inner face of the rear plate. Fig. 5 isa similar section, but showing the parts located within the machine onthe inner face of the front plate. Fig. 6 shows the pivoted plate NV andlatch X pivoted therein. Fig. 7 shows a side view of the same, and alsothe lever h and the stand to which it is hinged. Fig. 8 shows the latchX. Fig. 9 is a side view of the parts immediately connected with thearmature and armatnre-lever. Fig. 10 is a vertical transverse section ofthe die and box thereon.

The frame of the machine is composed of the front plate, A, rear plate,B, and four rods, a, at right angles to the plates and fastened to theplates by screws 1).

The electro-magnet O is supported by a stand, 0, on the outer face ofthe front plate, A. Its armature D is fixed on a lever, E, which ispivoted at d toastand, e, fastened on said outer face. The leverEextends through an opening in the plate A into the space be tween theplates A and B. A thumbscrew and nut, f, provide means for gaging thedistance of motion of the armature and armaturelever.

The die 9 is fastened on a support, h, which also guides the verticalpunch-rod 43. A spiral spring, j, on the punch-rod, between the upperpart of the support h and a collar, 70, on

the punchrod, presses the punch out of the die. Said collar, by comingagainst the lower part of the support h, gages the downward motion ofthe punch-rod. Above the die is a box, F, which is closed at all sidesexcept at the front.

There are two feed-rollers, between which the strip of paper which ispunched passes one, Z, fastened on a shaft, m, and the other, a,fastened on a shaft, 0. These shafts extend inward through the frontplate, A, and are geared together as shown, the bearings for the shaftsbeing supported by the front and rear plates, A and B. Provision is madefor a slight swinging motion vertically of the outer end of the shaft m,and hence -a vertical movement of the upper feed-roller, Z.

A shaft, G, having bearings at the ends in the plates A and B, has fixedthereon two wheels, which I call key-wheels. One, H, has teeth of theform of round pins, and the other, I, ratchet-teeth. On this shaft isalso a drum, J, preferably suitable to be revolved by means of thewell-known device of an endless chain and a weight. This drum isconnected with the key-wheel H by the ordinary ratchetwheel, pawl, andspring, so that the falling of the weight will cause the shaft G andkeywheels to revolve, while the weight may be raised without revolutionof said shaft and key-wheels.

A vertical shaft,K, having bearings in stands fixed on the inner face ofthe rear plate, B, has at the upper end a horizontal arm, p, and aboutmidway its length a worm, q, preferably of two parallel threads. Theshaft K is so located with reference to the key-wheel H and the wormthereon is such that the shaft K may be revolved by means of the wheelH. The key-wheel H has twice as many teeth as the key-wheel I.

A key, L, which is an arm formed at the outer end to be swung by eachtooth on the key-wheel I, is fastened at the inner end to a shaft, M,having bearings at the ends in the plates A and B. This key L has an armwhich extends through an opening in the plate A and under the punch-rodt, as shown.

Inamortisein the horizontal part of astand, N, fastened on the innerface of the plate A, is pivoted at or near its center a latch, 0. Insaid horizontal part, near the end thereof, is also an opening, in whichmay slide a vertical rod, r, which is pivoted at the lower end to thearmature-lever near its inner end. A rod, P, bent somewhat in the shapeof the letter 8, connects the armature-lever with the latch 0, beingpivoted to each. A spiral spring, Q, fastened at the lower end to an armextending downward from the armature-lever and connected at the upperend to the stand N by means of an adjusting screw and a nut, acts toraise the armature-lever, and hence to withdraw the armature from themagnet. A lever, B, is pivoted at the inner end to the stand N andextends under and in close proximity to the upper feedroller shaft, m.The outer end of this lever B is supported by the key L by means of ascrew, 8, adjustable in the end of the lever B.

On a shaft, S, having bearings at the ends in the plates A and B, is adrum similar to the drum J and connected with a gear, T, as the drum Jis connected with the key-wheel H. The gear T drives the feedrollers bymeans of a pinion on the upper roller-shaft, m, and an intermediate gearon another shaft, as shown. The gear T also causes rotation of avergewheel, U, by means of the intermediate pinions, gears, and shaftsshown. A verge is pivoted in suitable relation to the verge-wheel toengage therewith, as in ordinary clock-work, by means of a shaft havingbearings in the plates A and B. An arm, V, extends downward from theverge.

On the outer face of the plate B is a plate, W, which may swing in thedirection of the plane thereof, being pivoted at t, and being keptclosely against the plate B by the friction-rolls shown. It has at theouter end of one of its arm portions a pin, a,which extends inwardthrough an opening in the plate B. When the plate W is swung down to itslowest position, in which it is shown in the drawings, it rests on astand, 1), and it is pressed to that position by a spiral spring, to,acting against a lip on the plate W. When this plate is thus down, thepin a is out of engagement with the verge-arm V; but when it is swung upthe pin a engages with this vergearm to prevent its swinging motion andthe rocking movement of the verge.

In a mortise in the plate W is .pivoted at w a latch, X, at about midwayits length, to swing in aplane at right angles to the plate. A spring, 3pressing against the upper part of the latch X, acts to swing the lowerend of the latch out beyond the surface of the plate W.

A key, Y, which is an arm fastened at one end to a shaft, Z, is formedat the outer end to engage with the teeth on the key-wheel H. Near theinner face of the plate B is another arm, z, on the shaft Z, which,being bent at right angles at the outer end, extends through an openingin the plate B and has pivoted thereto the lower end of a vertical rod,a. This rod is guided at the upper part in an opening in a stand, asshown. Pivoted by means of another shaft, 1), having bearings in theplates A and B, is a long arm, 0, which carries at the outer end acam-piece, (1. Each of two pins, 6, on the side of the gear T may engagewith the cam-piece d in such a manner as to swing the arm 0 upward. Onthis arm 0 is also fixed a block, f, which extends through an opening inthe plate B, and to which is pivoted a vertical rod, '9, which, beingguided by an opening in the stand 12, may press against the lower end ofthe latch X when the latter is swung outward.

Near the upper edge of the plate B is hinged a lever, h, to a stand, t,fixed on the inner face of the plate B. This lever has two 1eaflikeportions at about right angles to each other, one, j, nearly vertical,extending down by the inner side of the plate B, and which may pressagainst a pin, is, extending inward through an opening in the plate Bfrom the upper part of the latch X. The other leaf or arm, Z, projectsoutward over the upper end of the vertical rod a.

While the circuit is closed the mechanism is at rest. The armature-leveris down, holding the rod 0" down out of the range of the arm p, and thelatch O in position, so that the arm p bears against the end projectingabove the stand N. The punch t is down out of the die g. The upperfeed-roller is pressed down onto the lower one by means of a spring,'m,which bears on the shaft of the upper feed-roller, the tension of whichis gaged by the screw and nut at a. One of the pins 0 on the gear Tholds the arm 0 up by means of the cam-piece (1, so that the arm 0 holdsthe plate W in its position when swung up by means of the rod 9, whichpresses against the projecting end of the latch X. Thus the pin u,engaging with the vergearm, prevents the rotation of the gearing and thefeed-rollers driven thereby.

Each of the keys bears against its key-wheel between the teeth thereof.When the circuit is broken the armature is released and thearmaturelever is swung up by the spring Q. The latch O is swung out ofengagement with the arm 1). The shaft K now makes one revolution, thearmp being first caught by the projecting rod 7' and then by theprojecting latch O, the rod r being raised on breaking the circuit, butlowered on closing the same and when the latch is raised. A revolutionof the shaft K allows the key-wheel H to move the distance of two teeth,and hence the key-wheel I on the same shaft one tooth. By means of thekey-wheel H, key Y, arm .2, rod a, and lever h the lower end of thelatch X is swung inward away from engagement with the vertical rod thusallowing the campiece (1 to be swung out of the way of the pin 0 on thegear T, and also the plate W to drop, so as to swing the pin u out ofengagement with the verge-arm V. The gear T may then revolve, causingrevolution of the feedrollers Z it. There being two movements of the keyY, caused by two teeth of the wheel H during one revolution of the shaftK, the revolution of gear T, and hence of the feedrollers, is stoppedtwiceonce at about the middle of the revolution of the shaft K and againat the end thereof. During this action of and by the key Y, the key L isswung by a tooth on its key-wheel, and raises the upper feed-roller fromthe lower one by means of the lever B, which is thus carried upward whenin contact with this roller-shaft. When the upper feed-roller is raised,there will be no movement of the paper. It may be, by suitableadjustment, either when the upper feedroller is raised or when thefeed-rollers are stopped, as set forth above, that the key L pushes thepunch-rod upward and causes the punch to pass through the paper andenter the die, and that the punch is withdrawn and the key Lretnrned toits former position by means of the spring 3'. i

The box F, being closed at all sides but the front, as described above,prevents the pieces of paper punched out from passing onto the paper,and provides for the ready removal of these pieces.

I claim as my invention 1. In an electric punch-register, thecombination, with two feed-rollers, the shaft of one of which may beswung as specified, of a toothed or key wheel, I, a lever or key, L, alever, B, provided with an adjusting-screw, s, to bear on the lever orkey L, a spring, m, and screw it, for gaging the tension of said spring,said key-wheel, levers, and spring being for swinging said shaft,substantially as shown and described.
